Study type: Medical/biological study (observational study)

Micronucleus assay and lymphocyte mitotic activity in risk assessment of occupational exposure to microwave radiation. med./bio.

Published in: Chemosphere 1999; 39 (13): 2301-2312

Aim of study (acc. to author)

To investigate the effects of micowave radiation on induction and frequency of micronuclei in peripheral blood lymphocytes of occupationally exposed subjects. The mitotic activity of lymphocytes was also studied.
